[摘要] 深圳市当代艺术馆与城市规划展览馆（简称”两馆”）为体型特别复杂的结构，包含大悬挑结构。由于大悬挑结构对人行激励可能会非常敏感，故需要对竖向激励产生的楼板振动问题进行分析。本文利用软件MIDAS/Gen进行分析，首先考察结构的竖向振动模态，再输入人行激励，求出楼板的共振频率及对应的峰值加速度，从而对楼板振动舒适度进行评判。

Abstract: The museum of contemporary art and planning exhibition of Shenzhen is a complicated structure, including large cantilever steel truss. It is necessary to study the structural vibration induced by pedestrian incentive. In this paper, software MIDAS/Gen is used to study the veItical vibration mode, and then the vibration load induced by human walking is applied to get the resonant frequency and the corresponding acceleration peak value to evaluate the vibration comfort of the slab.
Keywords: cantilever truss; pedestrian incentive, acceleration peak value; vibration mode
